The tournament rules state:
Taking Notes
Players are not allowed to take notes to aid memory or gameplay, whether physically or digitally, during a tournament match. Referencing outside material and information during a match is also prohibited, except for official rule documents.
I use tokens to mark the ice I have Femme'd both for me and the Corp. Is this allowed?
That's not "taking notes" and is exactly the sort of thing the red/purple tokens are included in the game for.

Exactly this.
"taking notes" is exactly what it sounds like. You're not allowed to write stuff down like what ice and/or servers you've exposed, what cards you've seen from an opponent's deck/hand, etc. and you also can't look at anything outside of the current game that might affect your decisions, outside of official rules/tournament guidelines documents.
